The present invention relates to the manufacture of yarn of articial origin but primarily has for its purpose to devise an apparatus for the wet treatment of large articial silk skeins.

In the wet treatment of large articial silk skeins, the ease with which the thread may be subsequently unwound after drying depends essentially on the uniform build-up of the skein on the reel. If a plurality of large artificial silk skeins are wound side by side upon ordinary reels as is done, for example, in the cuprammonium spinning process, it has been observed that with increasing. skein thickness the lower thread layers shift apart causing a disarrangement in the build-up of the skein, which may even cause thread layers to come in contact with adjacent skeins. The wet treatment of the said skeins after they have been removed from the reel causes considerable difficulties, and the dried skeins are exceedingly diiiicult to unwind. Owing to these troubles it was heretofore considered possible to produce only comparatively small skeins which must necessarily be laced in order to maintain the diamond Wind in the after-treatment. By using large skeins and eliminating the lacing operation certain obvious advantages result.

It has now been found that it is possible to insure a satisfactory build-up of the large skeins and even to omit the lacing of these skeins for the purpose of after-treatment if by means of suitable lateral supports on the bars of the reel the sidewise shifting of the inside skein layers can be prevented, and that further, contact of the lower yarn layers with adjacent skeins is avoided. y

It is therefore one object of the present invention to devise a reel for use in the winding of large skeins of yarn.

Another object of the present invention is to devise a reel provided with means which prevent the shifting of the layers of the yarn body.

These and other objects will in part'become obvious and will in part be pointed out when taken in connection with the accompanying drawing in which:

Figure 1 is a side elevation of a reel,

Figure 2 is a cross-section on the line 2-2 of Figure 1,

Figure 3 is a side elevation of one bar of a reel comprising the present invention,

Figure 4 is a cross section on the line 4-4 of Figure 3.

In accordance with Figure -1 of the drawing,

ill

shoulders I are formed integral with the bars 2 of a reel 3. The skeins are wound between the shoulder portions I. In this form of the device the shoulders l may be directly formed on metallic reels or they may be Worked out therefrom in any desired manner.

In accordance with the device forming the present invention as shown in Figure 3, the bar 2 of the reel has slidably mounted thereon a metallic sheath 4 which has formed therein separate transverse shoulders or protuberances 5. In this embodiment the sheath-like device `4 is removably mounted on the bar of the reel 2 whereby the sheath-like member 4 may be removed therefrom. These sheath-like devices may be made from acid proof metal or they may be made from acid resistant articial substances such as Celluloid, Bakelite, cellulose acetate and the like.

The connection between these removable sheaths 4 and the bars of the reel 2 may be accomplished in many ways, for example, as shown in Figure 4 they may be dove-tailed. The sheaths then may be easily slid over the bars of the reel and are easily removed therefrom whereby it is unnecessary to shift the bars themselves. It will be noted upon reference to Figure 3 that one end of each sheath 4 is formed to serve as a stop member 6 which will limit the sliding movement over bars 2. In view of the fact that each of the sheath-like members 4 is identical to every other sheath-like member, it is evident that when all of the sheaths are placed with their stop members 6 against the end 0f the respective supporting bars 2 each protuberance of each sheath will lie in the same plane as the corresponding protuberance of every other sheath. Thus, removable sheaths are provided, the protuberances of which may be aligned to function as skein separators. As can be seen in Figure 1, the ends of the supporting bars 2 all lie in a single plane at right angles to the reel proper so that the coaction with the stop members produces the above result.

The reels which have been provided with shoulders in the form shown in Figure 3 have wound in the usual manner thereon skeins of considerably greater size and Weight than those used heretofore in the art. The protuberances 0r shoulders support the skeins during the build-up on each side thereof and during the winding of the skeins the diamond is maintained until the Winding operation is completed. Without lacing. the skeins are then removed from the reel shown 1n Figure 3 of the drawing whereby the reel is slightly collapsed and the auxiliary sheaths together with the skeins are then drawn from the reel preferably in a horizontal direction. The skeins are then subjected in the usual manner to the Wet treatment and the drying operations and difficulties in the unwinding of the skeins are eliminated.

It is obvious that many variations may be made in the apparatus described herein, While utilizing the invention of the present application and it is not intended to restrict the invention to the particular descriptions or examples given herein. The terms used in describing the invention have been used in their descriptive sense and not as terms of limitation and it is intended that all equivalents thereof be included within the scope of the appended claim.

We claim:

In a reel for use in Winding yarn or the like including a plurality of bars disposed parallel to the axis and on the periphery of a geometric cylinder, said bars at at least one end of the reel al1 terminating in a single plane at right angles to the axis of said geometric cylinder, an axially slidable removable acid-resistant sheath extending for the operative length of each bar, each sheath being formed to cover the tops and sides of the respective bar and being provided with radially extending integral protuberances at spaced points along its length, each sheath having protuberances at the same points on its length, and stop means integral with each sheath and coacting With the end of the respective bar Which lies in the same plane as the end of every other bar to place each protuberance of eacll sheath in the same plane as the respective protuberance of every other sheath, whereby the sheaths may be removed without interference with accurate skein separation when in use.
